Hello Thank you for contacting HCM. There are chances of getting pregnant while using condoms only, as contaceptive technique during sex. I am assuming by the previous date u mentioned that you missed your period this time. You can take the urine pregnancy test.....and if it comes out negative I will advise you to take a re-test after two weeks have passed after missing your periods. i hope this answer your query. Please feel free to contact HCM again if you have any other concern. Wishing you good health.
